Data from: Genome-wide RAD sequence data provide unprecedented resolution of species boundaries and relationships in the Lake Victoria cichlid adaptive radiation

Although population genomic studies using next generation sequencing (NGS) data are becoming increasingly common, studies focusing on phylogenetic inference using these data are in their infancy. Here, we use NGS data generated from reduced representation genomic libraries of restriction-site-associated DNA (RAD) markers to infer phylogenetic relationships among 16 species of cichlid fishes from a single rocky island community within Lake Victoria's cichlid adaptive radiation. Previous attempts at sequence-based phylogenetic analyses in Victoria cichlids have shown...

Data from: Ecological opportunity and sexual selection together predict adaptive radiation

Catherine E. Wagner, Luke J. Harmon & Ole Seehausen
A fundamental challenge to our understanding of biodiversity is to explain why some groups of species undergo adaptive radiations, diversifying extensively into many and varied species, while others do not. Both extrinsic environmental factors (e.g. resource availability, climate) and intrinsic lineage-specific traits (e.g. behavioural or morphological traits, genetic architecture) influence diversification, but few studies have addressed how such factors interact. Radiations of cichlid fish in the African great lakes provide some of the most dramatic...

Data from: Lessons learned from microsatellite development for non-model organisms using 454 pyrosequencing

Microsatellites, also known as simple sequence repeats (SSRs), are among the most commonly used marker types in evolutionary and ecological studies. Next Generation Sequencing techniques such as 454 pyrosequencing allow the rapid development of microsatellite markers in nonmodel organisms. 454 pyrosequencing is a straightforward approach to develop a high number of microsatellite markers. Therefore, developing microsatellites using 454 pyrosequencing has become the method of choice for marker development. Here, we describe a user friendly way...

Data from: Population genomic signatures of divergent adaptation, gene flow, and hybrid speciation in the rapid radiation of Lake Victoria cichlid fishes

Irene Keller, Catherine E. Wagner, Lucie Greuter, Salome Mwaiko, Oliver M. Selz, Arjun Sivasundar, Samuel Wittwer & Ole Seehausen
Adaptive radiations are an important source of biodiversity, and are often characterized by many speciation events in very short succession. It has been proposed that the high speciation rates in these radiations may be fuelled by novel genetic combinations produced in episodes of hybridisation among the young species. The role of such hybridisation events in the evolutionary history of a group can be assessed by comparing the phylogenetic relationships inferred from different subsets of loci....

Data from: Adaptive plasticity and genetic divergence in feeding efficiency during parallel adaptive radiation of whitefish (Coregonus spp.)

Bänz Lundsgaard-Hansen, Blake Matthews, Pascal Vonlanthen, Andreas Taverna & Ole Seehausen
Parallel phenotypic divergence in replicated adaptive radiations could either result from parallel genetic divergence in response to similar divergent selection regimes, or from equivalent phenotypically plastic response to the repeated occurrence of contrasting environments. In postglacial fish replicated divergence in phenotypes along the benthic-limnetic habitat axis is commonly observed. Here we use two benthic-limnetic species pairs of whitefish from two Swiss lakes, raised in a common garden design, with reciprocal food treatments in one species...
